Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Such as Figure 1 to Figure 6 As shown, the unilateral percutaneous vertebral body guide of the present invention includes a base plate 1, a positioning plate 11 and a mounting plate 4 are installed on both ends of the base plate 1, and a connecting column 201 is installed on one end of the base plate 1, and the connecting column 201 is installed on the On the positioning plate 11, a bracket 12 is installed on the positioning plate 11, wherein, in order to better determine the puncture position during the operation, the positioning plate 11 and the base plate 1 are both made of transparent materials and are provided with scales. The bottom plate 1 is provided with a first chute 13, the first chute 13 is provided with a puncture groove...

Abstract

The invention belongs to the technical field of percutaneous vertebroplasty forming, and more specifically relates to a unilateral percutaneous puncture vertebral body guider. The unilateral percutaneous puncture vertebral body guider comprises a bottom plate, a positioning plate and a mounting plate rotationally mounted at two ends of the bottom plate respectively; a bracket is mounted on the positioning plate; a first sliding groove is formed in the bottom plate. A puncture groove is formed in the first sliding groove; arc-shaped sliding rails are mounted on the bracket and the mounting plate; a guide mechanism is mounted on the arc-shaped slide rail in a sliding manner; the guide mechanism comprises a first mounting base; a second sliding groove is formed in the first mounting base; a first fixed seat is mounted on one side of the first mounting seat; a first preformed groove is formed in the first mounting base; a first adjusting wheel is mounted in the first preformed groove in ahinged manner; a guide cylinder is arranged in the first adjusting wheel in a radial penetrating mode, a second connecting rod is installed on an angle ring, a spirit bubble is installed on the secondconnecting rod, and an infrared emitter parallel to the guide cylinder is installed on the first adjusting wheel and used for solving the problem that medical staff and patients need to make contactwith rays repeatedly due to the fact that the number of times of fluoroscopy in an operation is large.

Description

technical field [0001] The invention belongs to the technical field of cutaneous vertebral body shaping, in particular to a unilateral percutaneous puncture vertebral body guide. Background technique [0002] Percutaneous vertebroplasty (PVP) refers to the percutaneous injection of bone cement into the vertebral body through the pedicle or outside the pedicle to increase the strength and stability of the vertebral body, prevent collapse, relieve pain, and even partially recover A minimally invasive spine surgery technique for the purpose of vertebral height. [0003] At present, for percutaneous puncture vertebral body shaping, it is necessary to repeatedly fluoroscopy to locate the puncture point and puncture abduction angle during the operation. The number of times of fluoroscopy during the operation is large, which leads to repeated contact between medical staff and patients and radiation, which is not conducive to medical staff and patients. the health of the patient. ...
